-# Draft.
+# This script shows how Nexus can request histories from
+# a particular time frame.  Such request must succeed via
+# two connection types: EBICS and x-libeufin-bank.  EBICS
+# ensures the fetching of fiat payments made to the regional
+# currency authority, whereas x-libeufin-bank does it for
+# the regional currency circuit.  Note: the time-framed
+# request is exceptional: it's used only after a complaint
+# from a user where they didn't get their funds as expected.
